Here's an intellectual challenge.

The purge takes place. Everyone is logged off. Ten minutes pass and the servers go back up.
Congratulations! You're in queue because the world is full!
It's full of people who literally just logged in. They're not going anywhere any time soon.
How is this supposed to improve queue times?

Either that or the World limit isn't dependent on how many people are actually logged in because queue # keeps dropping in which case I'm confused ¯\_(ツ)_/¯
